Answer :
(1) The initial rate when [A] is halved and [B] is tripled is, 0.288 M/s
(2) The initial rate when [A] is tripled and [B] is halved is, 0.096 M/s
Explanation:
The given rate law expression is:
![Rate=k[A][B]^2](https://tex.z-dn.net/?f=Rate%3Dk%5BA%5D%5BB%5D%5E2)
Now we have to determine the initial rate when [A] is halved and [B] is tripled.
The new rate law expression will be:
![Rate=k\times (\frac{[A]}{2})\times (3\times [B])^2](https://tex.z-dn.net/?f=Rate%3Dk%5Ctimes%20%28%5Cfrac%7B%5BA%5D%7D%7B2%7D%29%5Ctimes%20%283%5Ctimes%20%5BB%5D%29%5E2)
![Rate=k\times (\frac{[A]}{2})\times 9\times [B]^2](https://tex.z-dn.net/?f=Rate%3Dk%5Ctimes%20%28%5Cfrac%7B%5BA%5D%7D%7B2%7D%29%5Ctimes%209%5Ctimes%20%5BB%5D%5E2)
![Rate=k\times (\frac{9}{2})\times [A]\times [B]^2](https://tex.z-dn.net/?f=Rate%3Dk%5Ctimes%20%28%5Cfrac%7B9%7D%7B2%7D%29%5Ctimes%20%5BA%5D%5Ctimes%20%5BB%5D%5E2)
Given:
Initial rate = 0.0640 M/s
As, Initial rate = ![k[A][B]^2](https://tex.z-dn.net/?f=k%5BA%5D%5BB%5D%5E2)
= 0.0640 M/s
Thus,
Now we have to determine the initial rate when [A] is tripled and [B] is halved.
The new rate law expression will be:
![Rate=k\times (\frac{[B]}{2})^2\times (3\times [A])](https://tex.z-dn.net/?f=Rate%3Dk%5Ctimes%20%28%5Cfrac%7B%5BB%5D%7D%7B2%7D%29%5E2%5Ctimes%20%283%5Ctimes%20%5BA%5D%29)
![Rate=k\times (\frac{[B]^2}{4})\times 3\times [A]](https://tex.z-dn.net/?f=Rate%3Dk%5Ctimes%20%28%5Cfrac%7B%5BB%5D%5E2%7D%7B4%7D%29%5Ctimes%203%5Ctimes%20%5BA%5D)
![Rate=k\times (\frac{3}{4})\times [A]\times [B]^2](https://tex.z-dn.net/?f=Rate%3Dk%5Ctimes%20%28%5Cfrac%7B3%7D%7B4%7D%29%5Ctimes%20%5BA%5D%5Ctimes%20%5BB%5D%5E2)
Given:
Initial rate = 0.0640 M/s
As, Initial rate = = 0.0640 M/s
Thus,
Answer:
The temperature in degress Celsius is 52.25°C
Explanation:
According the equation:
The temperature is:
°C
The circulatory system and the respiratory system; The respiratory system takes in the oxygen which then goes into our bloodstream to help our cells convert it into ATP energy.
The mole ratio of the reaction shows that equal volumes of hydrogen gas will be produced by the two reactions.
<h3>What is the mole ratio of a reaction?</h3>
The mole ratio of a reaction is the ratio in which the reactants and products of a given reaction occur for the reaction to proceed to completion.
The mole ratio of a reaction is also known as the stoichiometry of the reaction.
The equation of the two reactions are given below:
From the equation of the reaction reaction, an equal volume of hydrogen gas will be produced by the two reactions.
Therefore, the mole ratio of the reaction shows that equal volumes of hydrogen gas will be produced by the two reactions.

Answer:
The experimental feature of the MALDI-MS technique which allows the separation of ions formed after the adduction of tissue molecules:
B) Velocity of ions depends on the ion mass-to-charge ratio.
Explanation:
- The option a is not correct as distance traveled by ions doesn't depend upon the ion charge rather it depends upon time for which you leave the sample to run.
- The option b is correct as velocity of ions depends on the ion mass-to-charge ratio because separation is done due to mass to charge ratio feature.
- The option c is incorrect as time of travel is not inversely proportional to the ion-to-mass ratio because the ion will move across the gel until you stop the electric field.
- The option d is not correct as electric field between MALDI plate and MS analyzer is though uniform but this feature doesn't allow the separation of ions.
